Fantastic, [tie] the DoorsOS compatible assembly shell for the TI92! works On my ROM 2.1 (I hope it runs on other roms too) Phoenix, Boulderdash and so on works. So download and test [tie] from our homepage now!!! BTW, all libraries and so on has to be recompiled and the DoorsOS.h has to be modified and the DoorsOS kernel too, since there are more RAMCALLS -- TriX http://mxm.ticalc.org
